Eroge no Sekai de Slow Life: Issho ni Isekai Ten'i Shitekita Yarisaa no Daigakusei-tachi ni Tsuihou Sareta node, Henkyou de Muteki ni Natte Shin no Heroine-tachi to Yoroshiku Yarimasu

The more you do it, the stronger you get!? Iijima Satoru. 32 years old. Virgin. Today, he was idly masturbating while listening to the vibrator of the woman living upstairs... but suddenly the ceiling collapsed, and the woman, completely exposed from the waist down, fell! And then... she landed on him...?! He suddenly found himself in another world... the world of an eroge, famous for its goofy setting. In this game, the heroines always have some parts completely exposed, whether it be their breasts, their lower bodies, or wearing thongs - a veritable paradise! What's more, Satoru has the skill "Ero Note." When the favorability rating of the person whose name you've written reaches the maximum, it becomes an unstoppable skill that allows him to do whatever he wants with them!
